So last week it was WEGA v ECM, neither of which you were going to buy, now its a Linea?!
I think that its in the ballpark of $5.5k.
What most people dont take into account is that lineas vary from being fairly crappy to being really awesome. I certainly wouldnt want to spend that much without knowing that it was at least as good as a GB-5, so factor in asking for the hybrid grouphead, PID and gicleurs. Maybe theyll even do the preheat/mix valve thing for you. Of course, the hybrid group is something that will need to be custom done for you at the factory.
Why not just get on the list for the GS-3? So much less d!cking around. Or take a look at the single-group Dalla Corte.
